Michael Carrick has signed a one-year contract extension at Manchester United.

Carrick has been one of Louis van Gaal’s best players since he returned from an ankle injury he suffered last summer.

The 33-year-old’s contract was due to run out in June, but the club confirmed at a press conference on Friday that the midfielder had extended his current deal by 12 months.

Carrick scored the second and set up Marouane Fellaini for the opener in United's 3-0 win over Tottenham last Sunday.

After eight months of trying, everything finally clicked into place for Van Gaal’s men.

They played with width, pace, and flair as they swept three goals past Hugo Lloris in little over 35 minutes.

Van Gaal was delighted with his team's performance, but he says it will count for nothing unless his men beat Liverpool in Sunday's grudge match at Anfield.

“We played very good in the first half and it was also good to have an evaluation that is very positive,” the Dutchman said.

“It’s also good for the players. But it says nothing when you lose the next match.

“But the next match is against Liverpool and Liverpool is not the ground that Manchester United has won a lot (at) so when we show it again in Liverpool then we are a little bit further (along), I believe.”
